Description

MULTI-POSITIONAL SMOOTHING MIRROR FOR VIDEO PROJECTION OPTICS
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U. S. Provisional Patent Application Serial No. 60/570,595, entitled "Multi-Positional Smoothing Mirror for Video Projection Optics" and filed May 13, 2004, which is incorporated by reference herein in its entirety.
FIELD OF THE INVENTION
The invention relates generally to a projection display and, in particular a smoothing mirror for a projection display.
BACKGROUND OF THE INVENTION
Some new projection televisions include a light engine. Such light engines use a piezo-electric actuator and a rocking mechanism to hit a smoothing mirror between two locations. One example of the smooth picture actuator is a spring-mass type system. The piezo-electric actuator is designed to multiplex a video image that is decomposed into two sub-images. When sub-image A is projected on the screen, a small mirror ~ 25 mm x 25 mm is held in position "A". Microseconds later, when sub- image B is projected, the piezo-electric motor is actuated and moves the rocker arm that the mirror is attached to into position "B". When the next sub-image "A" is projected, current is removed form the piezo device and a return spring, for example, moves the mirror and rocker arm back into position "A". In the presence of audible noise from speakers or shock waves that can be transmitted by someone walking across a floor, there can be transmission of these forces into the light engine and into the piezo-electric actuator device. It is not uncommon for the amplitude of these forces to be amplified as they are transmitted through the system of the television cabinet plastics and light engine. When these forces are transmitted to the piezo-electric actuator device they may be large enough to undesirably induce motion in the rocker arm that overcomes the spring force and allows the mirror to oscillate outside of its intended frequency
SUMMARY OF THE INVENTION
According to an exemplary embodiment of the invention, a projection display is provided with a light engine including a damped piezo-electric smooth picture actuating device. The light engine comprises a mirror and an actuator for positioning the mirror. The actuator includes a tilting means that cό'ϋples the actuator to the mirror. The tilting means has damping material attached thereto. The damping material may be a polymeric material.

DETAILED DESCRIPTION
According to an exemplary embodiment of the invention, a projection display , is provided with a light engine including a damped piezo-electric smooth picture actuating device. As shown in FIGS. 1 A-5, the projection display comprises a cabinet 10 that is formed from a molded plastic and comprises an electronic area 30, . a mirror 22 and a light box 20. A light engine 40 comprises an output end 40a from which a light pattern is projected and an electronic end 40b having a lamp and various electronic components therein. The light engine 40 is mounted with the output end 40a in the light box 20 of the cabinet 10 and with the electronic end 40b in the electronic area 30. As shown in FIG. 1 A a screen 12 is mounted over the light box 20 A removable front cover 14 (shown in FIG. 2) covers the light engine 40 and the electronic area 30, when it is installed on the cabinet 10. According to an exemplary embodiment of the invention, a light engine comprises a mirror and an actuator. The actuator includes a frame 100 (FIG. 6) within which is located a tilting means 105 for positioning the mirror (not shown). The actuator includes a tilting means that couples the actuator to the mirror. The tilting means 105 has damping material 110 (FIGS. 7A-7C) attached thereto. The damping material may be a polymeric material: In one embodiment shown in FIG. 7A, a round piece of shock damping material 110 is inserted into a circular opening in a coil or compression type spring 120 (tilting means) of the piezo-electric actuator. The shock damping material 110 may for example, be slightly larger in outer diameter than the inner diameter of the spring 120 to ensure positive contact is made around the perimeter of the shock damping material 110. The addition of the shock damping material 110 to the spring 120 eliminates the natural vibratory resonance that is inherent to coil, or compression springs. In another embodiment shown in FIG. 7B, the shock damping material 130 is overmolded to the center portion of the compression spring 135. In this embodiment, a spring may be placed in an injection mold and allow damping material to be molded into the center of the spring as well as encompassing the outside of the coils as well. This process may be applied over a portion of the middle of the spring in an area for example, approximating 3 mm. Another embodiment shown in FIG. 7C, may include the shock damping material 140 attached on the two ends 145, 146 of the spiing 143. This arrangement allows the center of the spring to be free floating and would dampen the coil spring directly at its interface with the mating parts of the actuator. Tests were performed on springs with and without shock damping material as shown in FIGS. 7A-7C. Prior to shock material installation, the small mirror exhibited unwanted vibratory oscillation at 100 Hz, 140 Hz, 200 Hz and 420 Hz when an audible sine sweep was applied to front speakers of the projection television. After the shock damping material was added to the tilting means, 'for example, the spring, the presence of the unwanted oscillation disappeared. The foregoing illustrates some of the possibilities for practicing the invention. Many other embodiments are possible within the scope and spirit of the invention. It is intended, therefore, that the foregoing description be regarded as illustrative rather than limiting, and that the scope of the invention be given by the appended claims together with their full range of equivalents.
